Application filed February 13, 1914, Serial No. 818,451.

To all whom it may concern Be it known that I, NATHANIEL D. HULL, acitizen of the United States, residing at Fort Vayne, in the county ofAllen and State of Indiana, have invented new and useful Improvements inLiquid-Dispensing Devices, of which the following is a specification. Iv

' This invention relates to devices for dispensing liquids wherein bythe deposit of a coin the operating mechanism is released and a measuredquantity of liquid is discharged from a storage tank.

The device is particularly adapted for use as a dispensing device forliquid fuels, such as gasolene where the storage tank isyburied in theground and the dispensing apparatus is on top of the ground or in abuilding, thereby eliminating the element of fire hazard.

-Among the many objects of my invention are to provide a simple andefficient device by which a measured quantity of liquid may be obtainedaccording to the size of the coin deposited in the device; the provisionof means for indicating the quantity of fuel in the storage tank and forautomatically lock- Specification of Letters Patent.

Referring-to the drawings, 1 is the top cap, 2 the upper part and 3, thelower part of the housing in which the operating meching the device fromoperation when the tank is empty; the provision of a novel form of pumpand actuating mechanism; novel means for automatically cutting oil thedelivery of the fuel when the amount supplied is that which the coinwhich has been deposited will purchase, and novel means for releasingthe locking mechanism upon the deposit of a coin, the device needing noattendant and being installed on a street or highway where it isaccessible to users of the fuel at any and I all times. I accomplishthese objects, among others hereinafter recited, by the novelcombination, construction and arrangement-of parts hereinafter setforth, one embodiment of which I have illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the dispens: ingapparatus, the housing being in section; Fig. 2, a plan view of thesame, thetop of the housing being in section; Fig. 3, a detail in planview of the mair plungers by which the pump mechanism is connected tothe operating devices and the measuring devices are controlled; Fig. 4,a longitudinal section of one-of the main plungers; Fig. 5, a verticalcross section on line 5-5 of Fig. ,l-the unlocking plungers and cointubes being T16. Shaft 16? is'borne by bracket 21, and

anism is mounted, parts 2 and 3 being secured together by bolts 8, thetop being suitably secured to housing 2. Suitably mounted in bearingsformed in the two side walls of houslng 2 is a 'revoluble shaft 5 whichpro ects through one wall and is provided at its projecting end with acrank 63, collars 6-1 and 65, removably secured to the shaft, preventinglongitudinal movement of the shaft. Secured to this shaft are asuitable. number of cams 7 and a circular rack 6. A pawl 9 pivotallymounted on a boss which is carried by housing 2, is adapted to engagerack 6. 'Pawl 9 carries a fixed latch 9 which is adapted to engage apawl 117 suitably mounted on bracket 40, which is carried by housing 2.(Figs. 1 and 2.) A spring 29 is connected to pawl 117 and to the housing2 which opposes the movement of the pawl. In bearings 11 is supported arevoluble shaft 66 on the lower end of which is a gear 10 which is inmesh with a gear 62 secured to shaft 5. At the upper end of shaft 66 isa gear 12 which is in mesh with gear 13 loosely mounted on horizontalshaft 18, said shaft being carried by bearings 17 and 19 provided inbracket 17 which projects from frame 11. The opposite side of gear 13forms one j aw 13 of a clutch which is adapted to be-engaged by theother clutch jaw 14 suitably secured to shaft 18, a spring 116 betweenthe two jaws of the clutch opposing the connecting movement of the same.The opposite end of the jaw 14 is provided with a gear 15 adapted to bebrought into mesh with gear 16 which is secured to shaft drum 20 is alsosecured to shaft 16*, upon which drum a cable 22 is adapted to be woundasthedrum'is rotated by gear l6 as hereafter described.

Patented Mar. 28, 1916.

Jaw 14 is grooved peripherally and the groove is engaged by two pins 23fixed in the ends of yoke 55 (Fig. 1), the yoke being secured on shaft61 revolubly supported by housing 2. Secured to shaft 61 and projectingdownwardly therefrom are three levers 56 which are adapted to be rockedby three fingers 57 which project upwardly from three main plungers 30.The rocking of the levers rotates shaft 61 and, by

means of yoke 55, which moves with the shaft, the jaws of the clutch areforced together-to connect gear 13 to shaft 18 and gear 15 to gear 16whereby cable drum 20'is rotated and the pump is operated as hereafterdescribed.

On the opposite end of shaft 18 is secured a crank disk or wheel 24 towhich is suitably connected the upper end of connecting rod 33, thelower end of the rod being connected by crosshead and pin 44 to theupper end of plunger rod 48, which rod passes entirely through both topand bottom heads 47 of cylinder 46, suitable stuffing boxes beingprovided in the heads. A suitable piston or plunger is secured to rod 48and within cylinder 46 which is reciprocated between the cylinder headswhen crank disk 24 revolves upon the clutch jaws being connected asabove described. The pump is double acting, suction pipe 38 beingconnected to the cylinder adjacent both heads thereof and discharge pipe49 being similarly connected to the cylinder. Suitable check valves 39are provided in the connections between suctlon pipe 38 and the cylinderand suitable check valves 72 are provided in the connections betweendischarge pipe 49 and the cylinder. All the check valves are entirelyoutside the cylinder.

Suction pipe 38 leads to a filter 84 which is arranged within housing 3,and which will be described hereinafter. A pipe 92 connects the filterto a valve 105, branch 106 of the valve being connected to' pipe 112which passes through an opening in the tank and. may be provided at itslower end with a suitable valve 113. A bushing 107 and flange 110,through which pipe 112 passes, prevent the escape of gases from :thetank.

Discharge pipe 49 is connected at its upper end to drum 50, by whichpipe the drum is supported, a lug 2 on housing 2 (Fig. 7) serving as apivot. Within the drum is an L shaped pipe or tube 76 having an L at itsouter end to which hose 51 is connected by a suitable coupling. Thecentral horizontal arm of the tube 76 is secured to the web of the drumand passes through a hub 7 9- formed' on the web,asufiicient space beingprovided between the hub and tube to admit of packing 79. -The end ofsaid arm is fitted into a collar 78 provided on the end of pipe 78 whichpipe is secured to an elbow in the upper end of pipe 49. The outer endof hub 7 9 is threaded and packing nut 77 is engaged on said threadedend of the hub and serves to force collar "('8 on pipe 78 againstpacking, 79 and render the joint between pipes 7 6 and 7 8 tight.

" A suitable spring 7 5 is secured at one end to lug 80 on housing 2 andis coiled about collar 59 on the opposite side of wall 59 being securedto the sleeve. A spring encircles the sleeve and bears at one end on,

wall 59 and at its other end on a flange 59 secured to the sleeve. Thesleeve prevents the nozzle from passing too far into the space A and thespring prevents injury to the-hose and jar to the several parts when thedrum winds up the hose. A beveled lug 50" is provided on the innerperiphery of the drum 50 and a pin 120 movably mounted on spindle 121carried by bracket 34 which is mounted on hearing .11, is in contactwith said inner surface of the drum and when the hose is wound up thepin bears against the vertical wall of the lug, thereby preventing thewithdrawal of the hose. Arod'25, secured to the pin 120, extendsforwardly and is connected to a lever 27 (Fig. 1) secured to a collar 27which is mounte .on

shaft 118, which shaft is mounted on housing 2. Another lever .27 isalso secured to collar 27 and is connected by rod 27 to pawl 9 (Fig. 1).Levers 27 are secured to shaft 118 and their lower ends are sopositioned relatively to the plu'ngers 26 that when a coin is droppedinto one of the plungers and said plunger is drawn forwardly by graspingknob 4 on said plunger the coin will strike the lever above that plungerand force it forwardly, thereby causing shaft 118 to rotate and elevatelevers 27 and 27 by which the hose, drum and main shaft 5 are unlockedand both may be freely rotated. I

The three plungers 26 are U shaped and are slidable in a casing 40. Nearthe rear end of each plunger is a suitable vertically arranged slot 26adapted to receive a coin, the plungerbeing shallow enough to permit thecoin to extend upwardly in the path of lever 27. Above each slot, in thenormal of the tube being secured to the housing 2,

.the housing having suitable slots (1, b, 0, therein which open into theupper ends of the tubes 26", and through one of which slots the desiredcoin is inserted. The three slots and also the tubes 26 are of differentsizes, according to the size of the coin intended to be used forcontrolling the operation of the pump. In the drawing the slot a,having. the numeral 25 on the exterior of the casing above said slot, isintended to admit a 25 cent coin, slot 6 a 50 cent coin and slot '0 asilver dollar.

In the bottom of casing 40 are slots 40 which lead into tubes 124secured to said casing, the lower ends of the tubes terminating abovesuitable receptacles 30 provided in the forward ends of main plungers30, which plungers'are U shaped at their forward ends and are slidablein frame 54 secured to housing 2. The forward end of each lunger 30 isopen so that one of the cams may bear against the face of a coindeposited in the receptacle 30' and enable the cam to force the plungerrearwardly as shaft 5 is rotated. The cams are arranged on the shaft sothat one of them will be effective to reciprocate one of the plungerswhen a coin is deposited in it.

Slots 54 are provided in frame 54 at suitable points such that when anyone of the plungers has reached the end of its rearward stroke the slot54 will be" in register with the open bottom of the receptacle 30*, saidreceptacle being substantially two alined grooves in the vertical sidesof the plunger, the bottom of the plunger or horizontal floor of theplunger being perforated between the groovesso that'when a coin isinserted into the grooves the lower edge of the coin will 40 rest on theupper surface'of the frame 54 and as the plunger is moved on the framethe coin will be brought into register with slot 54 in frame 54whereupon the coin will drop through said slot and through tube 35 whichis connected to frame 54, into box 37, which box is secured to the innerface of door 100, which door is hinged to the front side of housing 3and opens outwardly. Above each plunger 30 is a lever 41 which ismounted on shaft 73, the shaft being 'I'evolubly mounted in housing 2.Each plunger is provided on its upper surface with a projecting lug 42which as the plunger moves rearwardly strikes the lower end of the leverand rocks the upper end forwardly. Another lever 41 is secured to shaft73 and is connected by rod 41 to pawl 117 and the said movement of thelever insures the connection of awl 117 and catch 9 on pawl 9. Whenplunger 30 retracts as hereafter explained lug 42, strikes lever 41 androcks it forwardly, which in turn rocks lever 41 rearwardly. Thismovement of the lever disconnects-pawl 117 from catch 9 and the catch isfree to drop into contact with rac'k ,6 and lock the shaft 5. Theforlyard or retracting movement of any pluner 30 causes its finger 57 tostrike and rock lever 56 whereby yoke 55 disconnects the clutch jaws andconsequently shaft 18 is disconnected from gear 13.

Cable 22, which is-adapted to be wound upon drum 20, is secured at itslower end to a weighted frame 69. Three stop bars 67 are loosely mountedin frame 69 and extend upwardly through apertures in frame 54. The upperends of the bars are arranged close to the plunger bars 30 respectivelyand are bent to overlap the plungers. The extremity of each bar isturned downwardly and bears on the upper surface of the adjacentplunger. Each plunger has a recess 74 in its top surface, which when theplunger is moved rearwardly will pass beneath the extremity of thecorresponding rod 67, which extremity will drop into the recess andprevent spring 31 which encircles plunger 30 from causing the plunger toretract. Spring 31 bears at one end against an overlapping portion 54 onframe 54 and its other end against a collar 30* on plunger 30.

Rods 67 areeach suitably graduated to indicate prices or quantities ofthe liquid to be vended and stops 68 are adjustably mounted thereon. Thesteps will be arranged on the rods at the proper points according to thecoins which the device is adapted to receive at slots at, b and c. InFigs. 1 and 5 the lowermost stop is arranged at the 25 cent mark, the.intermediate stop at the 50 cent mark and the upper stop at the $1.00mark. When the pump is inoperation the frame 69 is elevated bv thewinding cable 22. If a 25 cent coin has, been inserted and itscorresponding plunger30 has been reciprocated until the rod 67 carryingthe stop arranged at the 25 cent mark has engaged the recess 74 in saidplunger,

' the frame 69 will rise on rods 67 and when it meets'the stop 68'itwill elevate the rod and disconnect it from the plunger and permitspring 31 to cause the plunger 30 to retract and throw out the clutch onshaft 18 and stop the pump immediately. If either of the other twoplungers 30 are reciprocated by the insertion'of the proper coin the rod67 associated withthe same will be the only one to engage-it, the othersbeing free, and the ascendingweight 69 will, as it meets the stops onthe other rod or rods 67 merely elevate the rod or rods withoutreleasing the rod connected-to, the particular plunger until theweightstrikes its stop.

A suitable opening28 is provided in the front of housing 2 at a suitablepoint, a glass plate being inserted in the housing to cover the same.Above this opening and on the inside of housing 2 is mounted a suitablespool 28 over which travels a ribbon 36, which ribbon passes through aclea't 125 fixed to the housing in the rear of opening 28. A weight 52is connected to one end of. the ribbon and a cord or wire 95 isconnected to the other end of the ribbon. This cord or wire95 passesthrough a pipe 94 which is connected to storage tank 111 by of storagetanks.

A lug 115 is secured at a suitable point on cord or rod 95, and beneathit, at the proper point, is arranged the forked end of a rod 104 whichrod extends upwardly and is connected by adjustable connection 114 to acord or rod 99. The upper end of this cord orrod 99 1s connected bycords or rods 98 to opposite ends of plate 96 which is supported byspring 97 to a suitable part of thehousing and in the rear of slots a,b, c. The plate is provided with downwardly projecting extensions whichare adapted to pass through suit-able slots in thetop' of tubes 26 orthe devices connecting said tubes to housing 2. When stop 115 strikesthe forked endof rod 104 it forces downwardly said rod and-itsconnections to plate 96 causing the projections on the plate to passbehind the slots a, b, 0 and close them.

The forked end of rod 104 will be so positioned that the stop 115 willmeet it when the tank is substantially empty or contains an insuflicientquantityof liquid to meet the value of the largest coin which the deviceis adapted to make use of.

The filter (Fig. 8) 7 consists of casing 84,,

to the upper portion of which suction pipe 38 is connected. The stop 83is detachable and is held in place by thumb nuts..81 carried by lugs 82which lugs are in swivel connection with case 84. A ring 85 remov ablyfits within the top of case 84 and between the ring and the curvedbottom of the case is a nest of suitably spaced screens 86, thecover ortop 83 bearing down on the ring to hold the screens in place. The meshof each screenis preferably different from each of the others; that is,the lowest screen 1 has a relatively coarse mesh, the one above it .afiner mesh, the one above that still finer mesh and so on, the topscreen havingthe finest mesh of all the others. The screens serve totake out dirt and water and other objectionable matter which may bedrawn up from the tank along with the fuel or other liquid to be pumped.The bottom of case 84 is provided with an annular dis.-

charge sleeve 87 a which carries at its upper end a deflecting hood 87.The lower end of sleeve 87 is connected by nipple 89 to suetion pipe 92,coupling 90 serving to connect the pipe to the nipple. Pipe 92 extendsthrough the open bottom of housing 3, the housing being anchored to asuitable foundation by bolts 91. As the liquid in the tank 111 is drawnthrough sleeve 87? it discharges against hood 87 by which it isdeflected downwardly and outwardly. The deflector will serve to separatesome of the foreign matter since it retards the flow of the liquid andgives the foreign matter an opportunity of settling. The screens,however, do catch the foreign matter and water and the same fall intothe bottom of the case where it may be withdrawn through bib cook 88.

The operation is readily understood. In the normal inoperative positionof the device unlocking plungers 26 are in their inner positions, mainplungers 30 are in their forward positions, shaft 5 is locked by pawl 9,shaft 18 is disconnected from gear 13 and hose drum 50 is lockedby pin120, the hose being wound u on the drum. The user will insert the coinlie desires in the proper aper ture a, b, or c-as, for example, aperture6. The coin passes down through the .tube 26",

which leads from the aperture b,'into the middle plunger 26, where-it isheld in a verger. The user then pulls outwardly on said plunger untilthe coin drops out of the plunger through tube 124 into the middle mainplunger 30, in which plunger the coin is heldsimilarly to the positionin which plunger 26 held it. -As1plunger 26 iswithdrawn the coin meetslever 27, rocking the same and the connected shaft 118 and also levers27 and 27 The movement of; the latter two levers unlocks the hose drumand the shaft 5 and the user draws" out the hose and inserts the-IlOZZlGT' into the receptacle in which he desires to place the liquidcontained in the storage tank. He then rotates crank 63 and shaft 5continuously in one direction. Cams 7 also rotate with the shaft,

1 through tube 35 into box 37. At this instant the upper end of themiddle stop bar 67 drops into recess 74 in the plungerand locks the samefrom retracting under the influence of spring 31. The throwing in of theclutch connects gears and 16 and cable drum 20 begins to wind up cable22 and to elevate weight frame (59. Crank disk 2% is also rotated andthe plunger is reciprocated in the pump cylinder to force the liquid inthe storage tank through the filter, cylinder, hose and nozzle into theusers receptacle. The liquid-continues to flow so long as the userrotates shaft 5 and until weight framemeets the stop on the middle bar67, which bar has locked the middle main plunger. During the ascent offrame 69 it met the stop set for the lesser quantity of liquid-the 25cent quantity in the present illustration, and elevated the stop bar towhich is connected, but, since said bar was not connected to itscorresponding main plunger 30,- said plunger not having been moved bythe rotation of its corresponding fc'am, the middle plunger which wasmoved i "gravity to its'lowermost position,

is not-affected by the elevation of said bar. When the weight frame 69meets the stop on the middle bar it elevates the same, therebydisconnecting it-from the middle plunger and the spring on said plungerinstantly drives the plunger forwardly to its normal position. Finger 57on the plunger again meets lever 56as the plunger moves forwardly, whichlever, through yoke 55, throws out the clutch and shaft 18 isdisconnected from gear 13, and gears 15 and 16 are separated. The pumpthereupon ceases to work, the cable'drum ceases its windingrotationfand'the weight frame 69 falls by the cable necessarily.unwinding with it. As soon as lug'4 2 meets lever 41 the latter isrocked to disconnect'pawl 117 from its engagement with latch 9 on pawl9, which pawl 9 drops into" connection with rack 6 on shaft 5 to lock-1the same from further rotation until another coin is inserted. The pawl9 and said drum and lock the in the unwinding direction, and until theflitsconnection to lever 2'? are, of sufficient weight to rotate, asthey descend, shaft 118 in the reverse direction. This movement of Ishaft 118 carries with it lever 27 which throws in pin 120 so that whenthe hose is permitted to be wound up on drum 50 by spring 25 the pinwill engage the lug 50 on drum from rotation pin is again released.Plunger 26 is forced back within the housing at any time after thepumpeeases to operate.

The quantity of liquid in the tank will be indicated by the ribbon'36and if the tank is empty the apertures a, b, 0 will be closed by plate96.

It will be apparent that. the coin apertures, tubes, the plungers, camsand lock bars may be multiplied as desired. I do not,

intend to limit the control mechanism by any one of contemplateproviding any of the operating three coins, but desirable numtheascending venient for the consumer.
